Great!

The silicon pouch is good quality, steady, I don't need it but it's nice and protective for the metal case, keeps it from opening in case you didn't close it properly. And zipper is good quality. Problem is that the texture grabs every little lint/dirt that's your bag. Otherwise, it's good.

Pouch fits nicely and protects the box from scratches. I say I am glad that I have it, and it was for free with my set, that is awesome.

I like the pouch to keep my container clean and have the peace of mind that it won't pop open in my purse. However because it's silicone it picks up dirt like crazy, I don't know if there is a way around this. Also it would be nice if the pouch was big enough to hold the straw as well. So it was more of an all in one type idea.
